I'm transitioning hobbies and selling off all my kart gear. I have a Racejet Weather Pod, attached via velcro to a Palm M100 + the Maxjet software and all the cables for $275. This is for the Rotax classes. I've included a few links below for your research. Always stored inside and in airtight container with moister absorbing packet and without batteries.http://www.g-rpm.com/html/racejet.htmlhttp://www.g-rpm.com/html/maxjet_rotax.html
